Patent JP-S5985395-A (JP)
Title: Solder
Inventor: SHIMIZU SHINKICHI
IPC: C04B41/88
Filed: 1982-11-08
Abstract: PURPOSE:To avert the erosion of an electrode composed of silver/Pd by solder and to prevent melting of the solidified solder in the stage of packaging by decreasing the content of the tin in the solder composed of lead, tin and silver to be used for a terminal electrode of a multilayered ceramic capacitor or the like and increasing the m.p. CONSTITUTION:Solder consists, by weight of 90-97.5% lead, 8-1.0% tin, 2- 1.5% silver and has 280-296 deg.C melting region. A multilayered ceramic capacitor consisting of dielectric materials 1, 3, an internal electrode 2 and an electrode 4 formed of silver/Pd is dipped in a solder dipping tank contg. the molten solder thereby forming preliminary solder 5A and solder 5B fixing a lead terminal piece 6. Even if the dipping time increases in this stage, the silver of the electrode 4 is not eroded by the solder. The need for reducing the dipping time or for increasing the thickness of the electrode 4 is eliminated. Since such solder forms the high temp. solder, the melting of the solder 5B in soldering in the stage of packaging the printed circuit board is obviated.

Title: Continuous manufacture of laminated sheet for electrical use
Inventor: YAMAGUCHI FUMIO
IPC: H05K3/02
Filed: 1987-08-05
Abstract: PURPOSE:To make it possible to speed up the impregnation of resin liquid and to reduce the generation of bubbles and voids by a method wherein base materials to be impregnated are brought into contact with the resin liquids under the state that the base materials are compressed individually and, after that, the base materials in contact with the resin liquids are released from their compressed states. CONSTITUTION:Base materials 1 are compressed by passing through pairs of rolls 6 and 6 so as to drive the air in the base materials out and, just after that, plunged in liquid wells 8. During the passing of the base materials through the liquid wells 8, the base materials 1 tend to restore their original shapes by their elastic forces, resulting in generating suction forces, due to which resin liquids penetrate in the interior of the base material 1. Thus, the decreases of bubble and void and the reduction of the time required for impregnation become possible.

Abstract: PROBLEM TO BE SOLVED: To safely take opening/closing actions by providing current/voltage detecting circuits detecting the current/voltage of a motor, a current change quantity calculating program, a power change quantity calculating program, and a comparing program. SOLUTION: When one of an up switch 7a, a down switch 7b, and an automatic switch 7c is turned on, the on-signal is inputted to a microcomputer 2 via an interface 9. The control signal is outputted to a motor driving circuit 4 based on the input signal, and the driving circuit 4 rotates a motor forward or backward. When insertion occurs, a load is applied to the motor 3, the current is increased, and the voltage is lowered. The microcomputer 2 checks whether the current change quantity exceeds a threshold value or not and whether the power change quantity exceeds a threshold value or not to detect the insertion. The microcomputer calculates the change quantities with a circuit 20 based on current/power change quantity calculating programs 22a, 22b and compares them with the threshold values. Proper opening/closing actions can be taken.

Title: Phase locked loop controller
Inventor: MATSUURA HIROSHI
IPC: H03L7/18
Filed: 1989-07-27
Abstract: PURPOSE:To shorten a lockup time by providing a charging circuit charged at the overshoot of a step response on an integration device. CONSTITUTION:An integration device B5 integrates an error pulse signal under a time constant by using resistors R1, R2 and capacitors C1, C2. A voltage is applied to the resistor R3 and the capacitor C3 to charge the capacitor C3 in the case of overshoot of a step response. The charged voltage acts like cancelling a voltage assumed to be caused in the absence of the resistor R3 and the capacitor C3 when the step response shows an undershoot, the oscillating voltage is converged early and the oscillation is made stable. Thus, the same frequency stability as a reference highly accurate crystal oscillation circuit is provided and the oscillation is converged with a fast lockup time, then the settling time by frequency settling switching is quickened.

Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce installation costs by forcing raw liquid into a group of filter plates having maximum hole diameter and successively forcing the filtered liquid into a group of filter materials having smaller hole diameters so that an auxiliary machine required for each of several filters can be commonly used. SOLUTION: Filter plates are, for example, divided into four groups in such a manner that diameters of holes of filter plates are made successively smaller in the order of the groups and raw liquid is forced into a group of filter plates each having maximum hole diameter and the filtered liquid therefrom is successively forced into groups of filter plates having smaller hole diameters. That is, filter plates 1 are divided into four groups so as to be parallelly interposed between movable frames 2 on a horizontal rod supported by a fixed frame 3, and the plates are tightened by movable head 4 using a hydraulic cylinder 5.  As a result, the filtration by filter plates having several different hole diameters can be carried out with only one set of filter plate open/closure mechanism, plate closing sealing mechanism, filter cleaning mechanism, solid-matter discharge mechanism, etc., and hence maintenance work can easily be performed at low cost.
